Hello students, hope you all doing great.

In this question we are given that sulfuric acid reacts with sodium carbonate to form carbon dioxide gas, water and sodium sulfate.
00:12
We are given that 41 .59 ml of sulfuric acid reacts with 0 .2372 gm and we are asked to find out the normality of sulfuric acid.
00:21
To find out normality first of all we will have to find out the number of moles of sodium carbonate.
00:27
So number of moles of sodium carbonate is equals to mass of sodium carbonate divided by its molar mass.
00:38
Mass of sodium carbonate is given as 0 .2372 gm and its molar mass is 105 .99 gm per mole.
00:49
From this we get that number of moles of sodium carbonate is equals to 0 .0022 mole.
01:00
Now from the reaction we can say that 1 mole of sulfuric acid reacts with 1 mole of sodium carbonate.
01:06
Since it is a neutralization reaction so we will need 0 .0022 mole of sodium carbonate to react with 0 .022 mole of sulfuric acid.
01:17
So from this we can say that number of moles of sulfuric acid is also equals to 0 .0022 mole...
